What happened to the 3 rings after the on ring was destroyed????..

Read english books(comics,storybooks any thing u like), use dictionary while reading,watch english movie and news channels in TV and try to speak with someone in english ....Eventually your english will get better....

Try reading some English tutorials before you start reading the books. How can you understand the book if you're confused with some of the English words, right? After having a bit of a background with the language, read some books. Simple books at first, and not the complicated ones and then progress to difficult books. Also try to talk with someone who speaks in English and tell him or her to correct your grammar. Eventually, you will learn how to speak and write English.

Thank you for your answer..is it in the chapter where Aragorn is wedded to Elrond's daughter???....

Thanks! Well, I don't really remember where it was mentioned. But maybe it's around the part when they were about to sail off and leave middle earth forever, probably? :)
